    摘要： An engine assembly includes a turbocharger and a fluid conduit thermally coupled to the turbocharger such that the coolant flowing through the fluid conduit can extract heat from the turbocharger. The engine assembly further includes an exhaust gas recirculation (EGR) system and a second fluid conduit thermally coupled to the EGR system such that the coolant flowing through the second fluid conduit can extract heat from the EGR system. The engine assembly also includes an engine head defining a coolant gallery extending therethrough. The coolant gallery is in fluid communication with the first fluid conduit and the second fluid conduit. Further, the engine assembly includes an exhaust manifold integrated with the engine head. The coolant gallery is thermally coupled to the exhaust manifold such that the coolant flowing through the coolant gallery can extract heat from the exhaust manifold.

    摘要： An internal combustion engine includes a cylinder block defining a cylinder, a cylinder head, and an exhaust manifold operatively connected to the cylinder head and configured to exhaust post-combustion gasses from the cylinder. The engine also includes a turbocharging system configured to pressurize an airflow for delivery thereof to the cylinder. The turbocharging system includes a low-flow turbocharger having a first turbine housing and a high-flow turbocharger having a second turbine housing. Each turbocharger is configured to be driven by the post-combustion gasses from the exhaust manifold in order to pressurize the airflow and discharge the pressurized airflow to the cylinder. The turbocharging system also includes a flow control device for selectively directing the post-combustion gasses to the low-flow and high-flow turbochargers. The turbocharging system additionally includes a cooling module configured to cool the second turbine housing. A vehicle employing such an engine is also disclosed.

    摘要： An engine comprises a cylinder head connected to a cylinder block; a cooling circuit including a pump, a heat exchanger, and a ventilation vessel; a liquid-cooled component, connected into the cooling circuit by a connecting line and arranged between the pump and the ventilation vessel, which is cooled when the engine is not in operation; and a valve which is self-controlling as a function of coolant pressure arranged in the connecting line between the pump and the ventilation vessel, the valve adjustable between a first working position having a first, relatively small cross section of the connecting line, and a second working position, having a second, relatively large cross section of the connecting line, the valve controlling coolant throughput, wherein when the engine is not in operation and coolant pressure is reduced, the valve is in the second working position to provide an enlarged flow cross section.
